I agree with the folks who commented that a properly functioning player
should not be destroying rolls.  That being said, music rolls that see
a lot of use _do_ show wear.

At the Scott Joplin House State Historic Site in St. Louis, a restored
player piano is an integral part of the exhibits, and is played daily
by both visitors and museum staff.  The rolls get a lot of use, two in
particular: "Maple Leaf Rag" and "The Entertainer" are the two Joplin
compositions most requested by visitors.

These rolls _do_ show wear.  The end tabs are often the first to
go -- we have to order replacements frequently.  Edge wear is minimal
but you do see a bit of it on the leaders, but nothing that affects how
well the roll plays.

The piano is in pretty decent shape.  The early Kimball player action
performs quite well, especially for never having an automatic tracker.
The only time I've seen it "eat" an old roll was when the roll flanges
were warped enough to shred the roll during rewind, which is not the
fault of the piano.
